"Decomposition and Composition 3" large class teaching plan 1 activity goal:
1. Feel the environment of the new class and experience the happiness of being promoted.
I know that I have grown up, and I am a child in a large kindergarten class. I have a sense of honor.
3. Team up freely, arrange seats, discuss and agree on new routines for activities such as life, games and study.
Activity preparation:
1, when children report for duty, please ask parents to guide them to know the location of the new class.
2, 2 name tags.
3. courseware.
4, marker, a white hand.
Activity flow:
1, know the new class:
(1) Question: Compared with the middle class, has our class environment changed?
(2) Discussion: Do you like our new class? Why?
By reading and speaking, I can know the location of my class, the facilities, articles and wall layout of my class.
It is beneficial for teachers to arouse children's interest in observation through these methods, and then express their ideas in their own language.
2. Game: "Find a friend".
(1) Please find your own friends to form any group, and each group should have girls and boys.
The children flocked by themselves. Let's observe each other and see if there are boys and girls in each group. Then say: How many boys and girls are there?
(2) Please compare and line up six children in each group, with the short one sitting in the front and the tall one sitting in the back.
Line up and say, I am taller than anyone, so I am in front of Xiaoming and behind Xiao Li.
3. The game "Where is my' thing'":
The children first put their names on the small chairs, and then divided them into two groups: boys and girls. Choose a cabinet to put their clothes and other items, and put their own name tags on it.
Say, what floor is my stuff on?
4. Observe and understand the environment outside the classroom.
Question: Who are the neighbors of our class? What's on the field?
Activity expansion:
Children independently design new class cards, which can be posted at the door of the classroom.
The Design Background of Activity 2 in the Teaching Plan "Decomposition and Synthesis of 3"
Children's concentration is not high, their learning is not active enough, and their sense of participation is not strong.
moving target
1, decomposition of learning 3, synthesis of preliminary perception 3.
2. Enhance children's hands-on ability and oral expression ability.
3. Cultivate children's comparative judgment.
4. Develop children's logical thinking ability.
5. Guide children to actively interact with materials and experience the fun of mathematics activities.
Teaching emphases and difficulties
Decomposition and composition of 3
Activities to be prepared
Peach painting, the Monkey King, Pig Eight Rings headdress, crayons.
Activity process
One: Review the decomposition and synthesis of 2.
1, imported from Journey to the West and Song Dynasty
2. Give the child a name to dress up as the Monkey King, and the teacher will dress up as a pig and wear a headdress.
3. The teacher posted a picture of peaches on the tree and told the story of Pig Bajie picking peaches.
4. Fill in the blanks by naming the children
5. Let the children use gestures to express the decomposition and composition of 2.
Second, new funding.
1, the teacher explained the blackboard topic: decomposition and synthesis of 3.
2. The teacher told the story of Pig Bajie and the Monkey King sharing peaches. Children use colored pens instead.
Peaches are divided into one point.
3. The teacher asked the two children to play the Monkey King and Pig Bajie by name, and asked the children to report points by name. The teacher divided the peaches between the Monkey King and Pig and wrote on the blackboard.
4. Teachers and students use gestures to show the decomposition and composition of 3.
Third, extended activities: game activities "guess"
Four. abstract
Children, think about the breakdown of what we have learned today. ! Said by: Qu Lao. Teacher! How many ways can it be divided?
Teaching reflection
Learning decomposition and synthesis within 3 is an important idea for students to understand division and combination, and it is also a common method to understand the objective world. Let children know the composition of numbers and experience division and combination in operation. All the examples and exercises are to divide several objects into two parts first, then solve the abstract components of the objects and understand the composition of numbers from the decomposition of numbers. Through such activities, children are constantly experiencing separation and integration, and they feel that separation and integration are both different and related. From the point of view of doing problems, children will know such problems.
